switch case statement in c language

#switch case statement:- Swich case is the alternative of else if statement of C language . When we have many choices in our program & we want , user to choose one of them we may choose you 'switch case' to write the program for the same .

The switch case statement :-

switch (condition)

{

case 1:

-// set of statement

break;

switch (condition)

{

case 2:

-// set of statement

break;

switch (condition)

{

case 3:

-// set of statement

break;

switch (condition)

{

case n:

-// set of statement

break;

~~ In switch case the value of expression is pass than the value of expression is matched with each case one by one from starting to end . if value of expression is matched with any of the cases then statement or set of statement of that case will be executed and rest of the case will be bypass . If non of the case is matched then their may be default case wich will be executed . the break keyword is used in switch case to send the control out side of switch.

EXAMPLE:-

Program:- wap to choose any number by user in c language.

#include<stdio.h>

#include<conio.h>

main()

[

int a;

clrscr();

printf("choose any number from 1 to 4");

scanf("%d",&a );

switch case (a)

{

case 1:

prinf(" u have enter one");

break;

case 2:

prinf(" u have enter two");

break;

case 3:

prinf(" u have enter three");

break;

case 4:

prinf(" u have enter four");

default ;

printf("worng entry try again ");

}

getch();

}

Output :-
